Sam Ruby found this recipe. Seems possible, but not portable to Win95/98 (according to the comment, not sure that matters).

---------------------------------------------------------------------
        Key: GUMP-50
    Summary: A portable/robust lock is needed (that the OS cleans up)
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Gump
 Components: 
             Python

   Assignee: 
   Reporter: Adam Jack

    Created: Wed, 14 Apr 2004 7:43 AM

Description:
A lock is required so two gump processes do not run at the same time, and conflict. The mechanism employed today is flawed in that the OS can not clean up the lock on process termination, so we get stray locks left around.

P.S. Eventually we ought lock the workspace, and ensure that two workspaces can run simultaneously. Right now even that is not true, with use fo $GUMP/tmp.
